Developing new Schiff base molecules for selective colorimetric sensing of Fe3+ and Cu2+ metal ions: Substituent dependent selectivity and colour change
Abstract New Schiff base chemosensors (1–5) based on aryl ether amine were synthesized and explored the colorimetric sensing of metal ions. A highly selective colorimetric sensing of Fe3+ ions wasExpand
Selective fluorescence sensing of Mg2+ ions by Schiff base chemosensor: effect of diamine structural rigidity and solvent
Highly selective strong turn-on fluorescence for Mg2+ (Φ = 0.03 to 0.57) was realized with a simple Salen based Schiff base chemosensor (1a) using dimethylformamide (DMF) or dimethyl sulfoxide (DMSO)Expand
Halochromic Isoquinoline with Mechanochromic Triphenylamine: Smart Fluorescent Material for Rewritable and Self-Erasable Fluorescent Platform.
TLDR
Rewritable and self-erasable fluorescent platform has been achieved by make use of unusual fluorescence responses of PQPBA/TQPA with TFA/HCl after exposing NH3. Expand
Reversible fluorescence switching and topochemical conversion in an organic AEE material: polymorphism, defection and nanofabrication mediated fluorescence tuning
2-(4-(Diphenylamino)-2-methoxybenzylidene) malononitrile (DPAMBM), an organic aggregation enhanced emission material, showed an external stimulus mediated reversible phase change (crystalline toExpand
Self-Reversible Mechanochromism and Thermochromism of a Triphenylamine-Based Molecule: Tunable Fluorescence and Nanofabrication Studies
A triphenylamine-based fluorophore, 4-((4-methoxyphenyl)(phenyl)amino)benzaldehyde (1), exhibits external-stimuli-responsive self-reversible solid-state fluorescence switching, tunable fluorescence,Expand
Aggregation Induced Emission of Excited-State Intramolecular Proton Transfer Compounds: Nanofabrication Mediated White Light Emitting Nanoparticles
Excited-state intramolecular proton transfer (ESIPT) compounds, 2-(2-((2-hydroxybenzylidine)amino)phenoxy)benzonitrile (1) and 2-(4-((2-hydroxy-4-methoxybenzylidine)amino)phenoxy)benzonitrile (2)Expand
Selective turn-on fluorescence for Zn(2+) and Zn(2+)+Cd(2+) metal ions by single Schiff base chemosensor.
TLDR
Chemosensor based on Schiff base molecules were synthesized and demonstrated the selective fluoro/colorimetric sensing of multiple metal ions in acetonitrile-aqueous solution with different fluorescence λmax with clearly distinguishable color for both Zn(2+) and Cd(2+). Expand
Molecular Engineering of Triphenylamine Based Aggregation Enhanced Emissive Fluorophore: Structure-Dependent Mechanochromism and Self-Reversible Fluorescence Switching
Triphenylamine (TPA), a propeller-shaped optoelectronic molecule, has been used to generate stimuli-responsive smart fluorescent organic materials and correlate the effect of subtle structuralExpand
Drastic Modulation of Stimuli-Responsive Fluorescence by a Subtle Structural Change of Organic Fluorophore and Polymorphism Controlled Mechanofluorochromism
Stimuli-responsive fluorescence modulation of organic fluorophores is closely related to their structural organization, noncovalent interactions, ability to adopt different conformation, and phaseExpand
Substitutional group dependent colori/fluorimetric sensing of Mn(2+), Fe(3+) and Zn(2+) ions by simple Schiff base chemosensor.
TLDR
Simple Schiff base chemosensors were synthesized and demonstrated substitutional group dependent colorimetric sensing of metal ions and effect of substitution on the fluorescence selectivity of Zn(2+) has also been investigated. Expand
